In Canada December 2, 1936 1 Claim. (C1. 20-69) The present invention relates to improvements Il preferably arranged at an lobtuse angle with in Weather strip construction 4for doors, Windows one another. Y and similar closures. Y The fastening flange ID of the Weather strip is An object of the invention is the provisionA of formed, in cross section, so that it has an in- 5 a Weather strip which may be attachedk to a creasing taper from the juncture With thesealing closure Without the use of nails or other fastening flange to the outer free end. At the inner or elements. y y juncture end of the tapered'flange I0 isformed Another object of the invention is the provision a more abrupt short tapering portion I2 to inof a Weather strip which may be slidably concrease the flexibility of the strip at the juncture nected with a closure and may be easily mounted of the flanges. The sealing flange I I is preferably 10 in position and removed. of uniform thickness in cross section from the A further object of the invention is the proinner to the outer edge and usually of decreased vision of a weather strip which may be efficiently thiCkneSS relatiVe t0 the Complementary flange lll. employed on a straight as well as curved edge In order to properly connect the Weather strip closures. B with the desired edges of a door C, that is, the 15 still another object of the invention is the proupper and lower edges as Well as the free edge vision of a weather strip which will enable trimportion, eaoh Such edge of the door is preferably ming or planing of the edges of a closure to corformed With a comparatively Wide Shallow groove reet a warped condition without removal of the or channel I4 and relatively deep narrower groove Weather strip. I5. The deep groove I5 is preferably formed With 20 A stili further object of the invention is the a taper corresponding to that of the fastening provision of a Weather strip of the aforesaid chariange l0 0f the Weather Strip, that iS, having an acter which will provide a durable Weather-tight increasing taper inWardly 0f the dOOr. joint. To mount the weather strip B on the door it is,

Other objects and advantages of the invntherefore, merely necessary to slide the .same 25 tion will become apparent as the description longitudinally along the edge With the tapered progresses. flange I0 engaging the deep groove in the door.

In the accompanying drawing forming a pal-1; When the door is open, the exterior or sealing of this specification and in Which'like reference flange ll tends t0 aSSllIne an OlltWardly direeted characters are employed to designate correspondposition, at an inclination to the edge of the door, 30 ing parts throughout the Same; as shown at Figure 2. When the door is closed, Figure 1 is a perspective View of a door equipped the eXteriOr Sealing flange l l iS bent inwardly by with the improved Weather strip structure, the frame or casing structure, so that it assumes Figure 2 is a fragmentary 'perspective view a pOSitiOn approximately parallel With the edge showing the form of the Weather strip When the 0f the i001 and Within 0r partly Within the Wide 35 door is open, shallovv groove I4 of the door, as shown at Figure Figure 3 is a similar View showing the door in' 3; Due to the iiexible and resilient nature of the fully closed position in the door frame, Sealing flange, it pi'OVideS, in ClOSed pOSitiOn, a

Y Figure 6 is a fragmentary horizontal section If, due t0 the Warning 0f the door 01 Some through the Weather strip operatively connected Similar Cause, it beCOIneS neCeSSary t0 tl'iIn 0r 45 with awindovv, and plane one or more of the edges equipped with Figure 7 is a fragmentary perspective view the Weather strips, such planing operation may showing the weather strip connected withacurved be effected without removal of the strip, due to closure. the peculiar connection thereof and the fact that Referring to Figures 1 to 4 inclusive illustrating the blade in the plane Will not cut the rubber. 50 the application of the strip to a conventional When, due to such trimming or to partial wear swinging door, B generally designates the of the weather strip it should no longer fit as Weather strip which is formed of resilient iiexible tightly as may be desired, adjustment may be material, preferably rubber. The strip B is comeffected by inserting a filling strip I6 in the deep posed of a fastening flange I0 and a sealing flange groove I5 of the door, that is, between the inner 55 2Y Y end ofthe Weather strip fastening flange l0 and the inner Wall of the groove, as shown at Figure Y 5, so as to partially project the strip Vtransversely of `the door and to cause the exterior sealing flange to more. tightly engage the door frame.

As shown at Figure 6, the Weather strip B'may be connected in a similar manner to a sliding Window sash I8, in this case the sealing flange being retained Vinaa resilient, inwardly pressedY position approximatelyV parallel With each side edge of the sash to afford a slidable Weather-tight connection. i

At Figure 7 isV illustrated a corresponding connection of the Weather strip Bin aV closure, as for instance, Ya disc-type swinging vWindow 25 mounted in a frame 2| providing a round Window opening. Due to the flexible vresilient action of the correspondingly shaped groove in the edge Y portion of the closure. Due to the resilient nature of the strip, and particularly the exterior sealing flange, a very efcient tight-tting joint between the closure and its frame or casing is thus provided.

It is tobeunderstood that the forms of my invention herein shown and described are to be taken as preferred examples of theVV same,and

Vthat various changes as to the. shape, size and arrangement of parts may be resorted to. without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claimzn Y In a weather strip made entirely of rubber, an

elongated base pad adapted to be connected with a carrier member,and a flexible flange formed integral With the base and extending angularly therefrom, the said flange being of substantially uniform thickness, said base having a thickness equal to that of the angeat their meeting point and increasing in thickness gradually from that point for a short distance andg'then at amore obtuse angle in'order .to increase the base thick-` ness gradually to `a tapered form.
